Part A)
The answer is b) this is qualitative because the responses are about whether people are satisfied or not, instead of something numeric.
Part B)
The answer is b) this is random because it represents a different person in the sample, and it is variable because people feel differently about their situations.
I'm not sure about this but will give it a try:
Let f(n) = 2xⁿ - 2
Then f(3) = 2x³ - 2
So, f(2) = 2x² - 2
Answer:
Step-by-step explanation:
R = 3x + 9y
They told us that R = 7, y = 6
So you can rewrite the equation as:
R = 3x + 9y
7 = 3x + 9(6)
7 = 3x + 54
Subtract 54 from both sides.
7 - 54 = 3x
-47 = 3x
To find x, you need to divide both sides by 3
3x = -47
x = -47/3
Let the three consecutive integers be x , x+1 ,x+2
Given, sum of three consecutive integers = -126
x +x+1+ x+2 = -126
3x +3 = -126
3x = -126 -3
3x = -129
x = -129/3
x = - 43
x +1 = -42
x +2 = -41
The measure of angle CED is y. The correct option is the second option- y, because Triangle ABC is <u>similar</u> to triangle EDC
<h3>Similar triangles </h3>
From the question, we are to determine the measure of angle CED
In the diagram, we can observe that ΔABC is <u>similar</u> to ΔEDC
This is by the Angle-Angle similarity theorem
The theorem states that
If any two angles of a triangle are equal to any two angles of another triangle, then the two triangles are similar to each other
Thus,
Angle CAB = Angle CED
In the diagram,
Angle CAB = y
∴ Angle CED = y
Hence, the measure of angle CED is y. The correct option is the second option- y, because Triangle ABC is <u>similar</u> to triangle EDC
